Resumen

In this paper, one technical gap related to the indirect model predictive control (MPC) is discussed. This technical gap corresponds to the performance of such a controller to deal with distorted grid voltages and a significant computation delay through the feedback regulation loop. A basic case study involving a traditional 3-level h-bridge and a first-order output filter was considered in order to magnify the effect of time horizon prediction and voltage over the regulated grid current waveform. A comparison related to the covered MPC controller (in two different forms) and a classical discrete-time proportional-integral (PI) controller is performed by means of the achieved total harmonic distortion (THD) values. Simulation results from a model built on PSIM/Powersim are presented and discussed. It can be concluded that the MPC controller offers a wider operating range with stable conditions and lower measured values of THD from regulated grid current. And such kind of special feature becomes even more evident if a significant computation delay at the feedback control loop must be overtaken.
